If you have a multimeter handy, try measuring the resistance across the pickup, i.e. between the hot and ground leads. For the Lace Hot Gold, it should be about 6.0 Kohms, from what I see HERE. The best way to do this would be with the leads disconnected from the guitar, but if you want a quick diagnostic reading, you can use THIS METHOD.

An infinite resistance would indicate an internal break in the pickup somewhere, whereas a significantly lower resistance would indicate a short.
